Abstract
A surface-activated functional material and a method of producing the same are disclosed. The surface-activated functional materials are produced by subjecting a surface of a metal substrate to an activation treatment to change an atomic configuration of the metal substrate into an activated state and then adsorbing a second metal element to the surface of the metal substrate to preserve the activated state.
Claims32
A surface-activated functional material comprising a substrate of a metal exhibiting catalytic properties when activated, the atomic configuration of which is activated by excitation, and a second metal element adsorbed to the surface of said metal substrate so as to preserve the activated state of said metal substrate;
- the surface of said metal substrate consisting of an outermost layer composed only of atoms of said metal substrate, said outermost layer having lattice holes, and a second layer beneath said outermost layer composed of atoms of said metal substrate and atoms of said second metal element adsorbed in lattice holes defined by surface migration of atoms of said metal substrate during the excitation such that less than one monolayer of said second metal is adsorbed to the surface of said substrate.
A method of producing surface-activated functional materials, which comprises subjecting a surface of a metal substrate to an activation treatment to excite the atomic configuraton of said surface of said metal substrate into an activated state, and then adsorbing a second metal element to the surface of said metal substrate while said atomic configuration remains excited, less than one monolayer of said second metal being adsorbed to the surface of said substrate to preserve said activated state.
